Fish That Should Not be Treated With Copper

ritter6788 · Jun 22, 2012

I've never seen one posted anywhere but I think it would be great to have a list of all the fish that will not tolerate copper or that are very sensitive to copper treatments. I'm no expert on this so please chime in with any fish you know of, or have experience with that should not be treated with copper medications.

I'll start with ones I do know.

Sharks
Rays

Any fish that are scaleless (mandarins) should not be treated with copper since they can not get ich anyway.

Got this from another site;

Some fish like Mandarin’s are considered highly resistant to ich – probably because of the thick mucus lining. Being less susceptible to ich does not necessarily make them immune from ich … Mandarins as examples are less likely to be infected – but they can be infected and have been known to die from ich.
